It's been a long time since I read the book, but I'm pretty sure half this shit was not in it.
I don't mind that it's not a wholly faithful adaptation, but when part one of a three-movie series is this boring, it does not bode well.
One of the things the heavy reliance on CGI did was highlight just how ridiculous some of the D&D tropes that evolved from Tolkien are. Like dwarves taking on trolls. I completely failed to believe a bunch of dwarves, however bad-ass they may be, beating monsters made out of pure muscle mass several times their size in close combat. Now granted, complaining about a lack of physics in fantasy RPGs is rather missing the point, but when you put it in a movie, it starkly illustrates how fantastical and ridiculous it is.
I don't care if they're all 12th-level fighters, one troll would stomp the lot of them into the ground.
I did like the part with Gollum.

Gandalf help me, I think I preferred the 1977 Rankin-Bass version.
